Digital Desk: Gaganyaan, India's ambitious first human spaceflight project, will fly its first test vehicle mission to validate the crew escape system in about two months, a top ISRO official announced on Friday.
It would be the first of the four Gaganyaan program missions that were aborted, according to officials of the National Space Agency, which has its headquarters in Bengaluru.
The second test vehicle mission, TV-D2, and the first uncrewed mission of Gaganyaan (LVM3-G1) would come after the first test vehicle mission, TV-D1.
The next missions are the LVM3-G2 mission with a robotic payload and the second set of test vehicle missions (TV-D3 and D4). According to them, the successful test vehicle and uncrewed missions served as the basis for the crewed mission's planning.
"Right away, the crew escape system validation is what we are targeting for. The project will launch from Sriharikota in a month or two," Gaganyaan Project Director R Hutton announced at an international space conference here.
According to ISRO officials, the Gaganyaan project aims to show India's capability of sending a crew of two to three people on a one- to three-day mission to a circular orbit of about 400 km around the Earth and returning them safely to Earth by landing in a predetermined spot in Indian sea waters.
The launch vehicle for the Gaganyaan mission has been identified as the LVM3 rocket, ISRO's heavy-lift launcher. A solid stage, a liquid stage, and a cryogenic stage make up this system. All systems in LVM3 are re-configured to meet human rating requirements and are christened Human Rated LVM3 (HLVM3).
"I'm happy to report that the LVM3 has received human ratings when we say human-rated, it should have adequate safety margins," Hutton stated during the conference, which was organized by the Confederation of Indian Industry.
A series of quick-acting, high-burn-rate solid motors are used in the Crew Escape System (CES) of the HLVM3 to ensure that the Crew Module (CM) and crew are transported to a safe distance in the event of an incident on the launch pad or during ascent.
The Crew Module and the Service Module are parts of the Orbital Module (OM), which will orbit the Earth. Modern avionics systems with sufficient redundancy for human safety are installed on OM.
The crew can live in CM, which has an Earth-like environment for the crew. A pressurized metallic inner structure and an unpressurized external structure with a thermal protection system make up its double-walled architecture.
It houses the deceleration systems, avionics, life support systems, crew interfaces, and human-centric goods. To guarantee the crew's security during descent and touchdown, it is also built for re-entry.
SM will be used to give CM the assistance it needs while in orbit. A heating system, a propulsion system, a power system, avionics systems, and deployment mechanisms are all contained within the unpressurized framework.
